Backed by research
We use metrics from academic papers and established investing research, not hidden scoring formulas.
Other screeners stop at past-year returns. Factor Screener checks every possible rolling-return window and outperformance metric, so you can see which funds keep beating their benchmark again and again.
Built differently
We go beyond simple 1Y, 3Y, and 5Y return tables with rolling returns, benchmark beat rates, and outperformance consistency across thousands of time periods.
We use metrics from academic papers and established investing research, not hidden scoring formulas.
See how often, how consistently, and by how much a fund outperformed instead of relying on one lucky trailing-return snapshot.
Start with the full mutual fund universe, then narrow it with a focused set of research-backed signals.
Compare passive funds by investor-relevant tracking results, or scan stocks with proven momentum research before you go deeper.
We skip tracking error and focus on what investors actually experience: tracking difference and the spread of fund returns.
Compare index fundsWe combine the academically proven 12-1 momentum factor with Frog-in-the-Pan research to favor steady, persistent price moves.
Explore stocksConsistency tells you how often a fund beat its benchmark. Quality adds the missing part: the size of those wins, the pain of losses, and whether the excess return was stable across rolling CAGR windows.
Each term is calculated from rolling CAGR excess return: fund rolling CAGR minus benchmark rolling CAGR. Higher is better, and the screener displays the result as percentage points.
Median excess CAGR carries the most weight, so a fund must win in the typical rolling window instead of relying on one strong period.
The mean is winsorized at the 5th and 95th percentiles, keeping unusually large one-off windows from dominating the score.
Downside pain, tail loss, and instability lower the score when a fund's outperformance comes with frequent or severe benchmark lag.
Not all the tools you need, but only the tools you need to make wise & effective investment decisions.
